Eugene and Cyndi, I agree that the best coral I saw was on the BB shark and ray excursion.
There's disagreement about the Moorea excursion which is similar--I found the coral to be in pretty bad shape, others thought the excursion was great, their very favourite. Maybe we went to different places, who knows?
I didn't mean to imply that the coral was great on the preservation trip, but the fish were.
